1 Claim. (Cl. 101-491),

This invention relates to an adjustable chase and'm-ore particularly toa chase for use in a printing press-for printing one or a very few linesof type slugs onsheets of paper-wherein it is desired to hold the paperin a stationary position and to locate the type l11-Vafi0US places onany particular sheet of paper or groups ofpaper.

In the printing of one or several lines of type on sheets of paper suchas pre-printed cards, such as greeting, cards and the like, it isnecessary to frequently change the type and it is also necessary toaccurately position the type relative to the paper. In the past, lockingthe type up in a conventional printing press chase has required a greatdeal of time and moreover, it has been difficult to position the typewithin the case so that the type prints in the proper location. In manycases, the printed moves the paper so that the paper is in a properposition for printing and keeps the type stationary, changing theposition of the paper as the job requires.

Thus, it is an object of this invention to provide a chase wherein thetype may be moved into various positions within the case so that thepaper upon which the printing is to take place may be held in a singleposition within the press and the type may be moved within the press forany particular run.

A further object of this invention is to provide a chase wherein thetype slug is adjustable within the chase to various positions andmoreover, wherein a releasable locking means is provided so that thetype slug or several linotype slugs may be quickly inserted into thechase and may be quickly removed simply by pushing the slug intoposition or by pulling the slug out of position.

These and other objects of my invention will become apparent uponreading the following specification of which the drawings form a part:

Referring to the drawings in which:

Fig. 1 is a top view of an adjustable chase formed in accordance withthis invention.

Fig. 2 is a cross-sectional view taken in the direction of arrows 2--2of Fig. 1.

Fig. 3 is a top view of the slug carrying frame which fits within thechase.

Fig. 4 is a view of a slug of type in an enlargement for illustrativepurposes.

The conventional printing press chase consists of a four-sidedrectangular frame within which slugs of type are held by means ofspacers which are locked into position by various locking means.

In this case, the conventional chase designated as is provided with apair of guides 12 and 12a, with the guide 12a being positioned more orless against one of the shorter sides of the chase frame and the guide12 being spaced from the opposite side of the chase frame. The guide 12is supported by means of a transverse bar 13 within the chase frame withbolts 14 rigidly connected to the guide 12 but slidable through openings15 in the transverse bar 13 and springs 16 which resiliently urge theguide 12 towards the center of the chase frame.

A third, slu'g' holding, frame '30' is arranged between.

The slug frame 30 holds a type slug 32 in position for printing with thetype faces 33 of the type extending above the fiat frame planes asindicated in Fig. 2.

In order to releasably hold the type slug in position, a locking bar 35is provided within the slug frame, spaced from the slug frame side 34,with the locking bar 35 being spring urged toward the side 34 by meansof springs 36 surrounding bolt 37. Here again, the bolts 37 are rigidlyconnected to the locking bar 35 but pass through openings 38 in the sideopposite the locking bar side of the slug frame. Fig. 3, illustratesthis construction,

per se.

It can be seen that with this type of construction, and particularlywith reference to Fig. 1, that the slug frame can be moved to the leftor right and will be held in position by means of a fiat presser barpressing the slug frame against the opposite side of the second frame.Likewise, the second frame can be moved upwards and downwards againstthe resistance of the spring biased guide 12 for positioning the type inan upward or downward position.

Moreover, the slug is normally considerably shorter than the length ofthe slug frame so that it also can be moved within the slug frame foradjustment where necessary, although normally, the slug is pushedtightly against the left side of the slug frame as indicated in Fig. 1.

In order to accurately position the type slug, indicia are provided onthe guide 12a, which indicia 40 indicates the position of the secondframe. For example, the top of the second frame can be used relative tothe indicia. For the same purpose, indicia 41 are provided on thepresser bar 22 so as to accurately locate the slug frame in its movementrelative to the presser bar. Again, the extreme left side of the slugframe could be used as a point for measuring the location along theindicia 41.

It can be seen that this construction utilizes the ordinary chase framefound on the printing presses but by the insertion of the second andthird slug frame and by means of the spring biased guide and presserbar, the interior frames can be moved so that the type slug can beadjusted upward and downward or left and right as seen in Fig. 1.

It is apparent, that the spring biasing means used for each of theframes could be modified in several ways such as, for example, by theprovision of blocks of rubber or other types of resilient urging meanssuch as a leaf spring or the like. It is important only that theresilient urging means be of sufi'icient strength to lock the framesinto position normally and yet be yieldable enough so that the framescan be moved when sufiicient force is applied to slide them betweentheir respective guides as shown.

This invention may be-further developed within the scope of thefollowing claims and accordingly it is desired that the foregoingdescription be read as being merely illustrative of an operativeembodiment of this invention and not in a strictly limiting sense.

Having fully described an operative embodiment of my invention, I nowclaim:

An adjustable chase for use in adjustably positioning a slug of type invarious positions for printing, comprising a first rectangular shapedopen frame having parallel spaced guides formed within the frame; springmeans and a presser bar between one side of the frame and one guide forbearing it towards the other guide; a second rectangular shaped framepositioned within the first frame and fitting between the guides andbeing considerably narrower in dimension in the direction parallel tothe guides for relative sliding movement within the first frame; and athird rectangular frame fitted within the second frame and being sodimensioned as to be freely slidable in the second frame in a directiontransverse to the guides; spring means and a presser bar between oneside of the second frame and the third frame for biasing the lattertowards the other side of the second frame; and releaseable lockingmeans in the third frame for holding a. type slug whereby said slug maybe moved parallel to or normal to the guides and may be releasablysecured in position within the third frame, said releasable lockingmeans in the third frame comprising a spring means, and a presser barbetween the slug and one side of the third frame for biasing the slugagainst the other side of the third frame.
